As it turns out, nomming on the occasional delicious, saturated fatty acid animal product is even worse for us than we thought it was. Not only do foods that are high in saturated fat (e.g. red meat, butter, whole-fat milk and cream, cheeses, etc.) clog the arteries and dramatically increase the risk of heart disease and stroke, but a new study in Annals Of Neurology, reported by The Atlantic, says that the consumption of saturated fat has a deleterious effect on the brain, thanks to the study of 6,000 women over the age of 65. It wasn't the total amount of fat consumed, but the type of fat that effected women's memory; during the four-year data collection period, women who ate nonsaturated/healthier types of fat, like the olive-oil based kind, scored higher on cognitive function tests. The jury is still out on whether it effects men in a similar way.
